[0028]
In the audio signal processing system 1000 described above, an audio signal is input from the
microphone 600 to the audio signal processing apparatus 200 via the connection board 300.
The audio signal processing device 200 is a mixer and performs signal processing for adjusting
the volume and sound quality to the audio signal. Then, the audio signal is output to the amplifier
400, amplified by the amplifier 400, and output from the speaker 500. Further, by the remote
control by the remote control device 100, the voice adjustment function of the voice processing
device 200 is controlled.
[0029]
The audio signal processing system 1000 of FIG. 2 can be implemented by making minimal
modifications to the conventional audio signal processing system shown in FIG. 14, as described
below. First, in FIG. 14, the mixer 1401 is installed at the side of the stage. On the other hand, in
FIG. 2, the audio signal processing apparatus 200 which is a new mixer is installed in the audio
equipment room. Then, the audio signal processing device 200 is connected to the remote
control device 100 beside the stage.
[0030]
Here, as a feature of the present embodiment, an audio signal is used for remote control from the
remote control device 100 as described later. Therefore, an existing voice transmission line is
used to connect the remote control device 100 and the voice signal processing device 200. That
is, the audio transmission lines 1406 and 1407 in FIG. 14 (the mixer 1401 beside the stage is
connected to the amplifier 1402 and the connection board 1403 in the audio equipment room)
become the audio transmission lines 710 and 720 in FIG. Thus, the remote control device 100
and the audio signal processing device 200 are connected.
[0031]
Further, the configuration of the remote control device 100 is realized by the function of
adjusting the volume and sound quality of the audio signal as described later. That is, the remote
10-04-2019
10
control device 100 can be realized by the function of the existing mixer 1401. Therefore, the
existing mixer 1401 can be used as the remote control device 100 as it is. In short, in the audio
signal processing system 1000 of FIG. 2, two mixers are disposed in the sound equipment room
and at the side of the stage. Then, the mixer in the audio equipment room processes an audio
signal such as an actual microphone input as a main device, and the mixer beside the stage
remotely operates the mixer in the audio equipment room as a remote control device.
[0032]
As described above, in the present embodiment, the existing voice transmission line and mixer
can be used for remote control. The configuration that makes it possible to use such an existing
configuration will be described below. As shown in FIG. 1, in the audio signal processing system
1000 according to the present embodiment, as a configuration for realizing remote control using
an audio signal, a reference audio signal oscillating unit 210 and audio measurement in the audio
signal processing device 200. The part 220 is provided. The remote control device 100 further
includes an audio input unit 110, an audio adjustment unit 120, an audio output unit 130, and
an operation unit 140.
[0033]
The reference audio signal oscillating unit 210 has a function of an oscillator that generates a
signal in the audio band, and generates an operation reference audio signal. The operation
reference voice signal is a reference voice signal for remote control. The operation reference
audio signal is a signal different from an audio signal such as a microphone input to be processed
by the audio signal processing apparatus 200. The operation reference audio signal is, for
example, a signal having a constant volume over the entire frequency range. The operation
reference audio signal is sent from the audio signal processing device 200 to the remote control
device 100 via the audio transmission line 710.
[0034]
The remote control device 100 is realized by the mixer as described above. Therefore, various
configurations such as the audio input unit 110, the audio adjustment unit 120, the audio output
unit 130, and the operation unit 140 are realized by the various functions of the mixer.
Specifically, the audio input unit 110 and the audio output unit 130 are audio input / output
10-04-2019
11
units of the mixer. The operation unit 140 is an operation unit for adjusting the volume and the
sound quality, and the operation unit is, for example, a rotary volume or a slide volume. The
sound adjustment unit 120 is an adjustment unit for volume and sound quality, and the sound
quality is a frequency characteristic, that is, a characteristic of volume change according to the
frequency.
[0035]
As described above, the remote control device 100 is realized by a mixer, but the difference with
the normal mixer is that the normal control device processes an audio signal such as a
microphone input while the remote control device 100 And process the reference audio signal
for operation from the audio signal processing device 200. The operation reference voice signal
is input from the voice input unit 110 and supplied to the voice adjustment unit 120. The voice
adjustment unit 120 adjusts the operation reference voice signal according to the operation on
the operation unit 140. Specifically, the volume and the sound quality of the operation reference
audio signal are adjusted. The adjusted signal is output from the audio output unit 130 to the
audio signal processing device 200 as an adjusted audio signal for operation via the audio
transmission line 720.
[0036]
The operation adjustment audio signal is input to the audio signal processing device 200 and
supplied to the audio measurement unit 220. The voice measurement unit 220 measures the
amount of change of the adjustment voice signal for operation with respect to the reference voice
signal for operation. The amplification factor of the audio signal is measured as the amount of
change. More specifically, the operation adjustment audio signal has its volume and sound
quality adjusted with respect to the operation reference audio signal. Then, the amplification
factor of volume and sound quality is measured. Sound quality is represented by frequency
characteristics, and changes in frequency characteristics are obtained as amplification factors for
each frequency. The amount of change obtained in this way corresponds to the amount of
operation to the operation unit 140 in the remote control device 100, and is used in the audio
signal processing device 200 as information on the amount of operation.
[0037]
10-04-2019
12
Next, a configuration for performing audio signal processing using the change amount of the
measurement result as the operation amount will be described. The audio signal processing
device 200 further includes an audio control unit 230, an audio information display unit 240, an
audio input unit 250, a signal processing unit 260, and an audio output unit 270.
[0038]
The voice control unit 230 generates a control signal to the signal processing unit 260 based on
the amount of change measured by the voice measurement unit 220. The control signal is a
signal for reflecting the operation of the sound volume and the sound quality (frequency
characteristic) obtained as the variation amount in the signal processing in the signal processing
unit 260.
[0039]
The audio input unit 250, the signal processing unit 260, and the audio output unit 270 are
configured to realize an input / output function and an audio adjustment function of the mixer.
The audio signal processing device 200 may be a digital mixer, and the signal processing unit
260 may be a DSP (Digital Signal Processor). The signal processing unit 260 processes the audio
signal in accordance with the control signal from the audio control unit 230. Thereby, the
operation in the remote control device 100 is reflected in the signal processing.
[0040]
The audio information display unit 240 is controlled by the audio control unit 230 to display the
audio adjustment state in the audio signal processing device 200, that is, the adjustment state of
the volume and the sound quality, and is configured by a display, an LED, etc. Be done.
[0041]
The configuration of each part of the audio signal processing system 1000 has been sequentially
described above.
In addition, the audio signal processing system 1000 has the following calibration function. In
10-04-2019
13
the calibration, in the remote control device 100, the operation unit 140 is set to a
predetermined calibration position. For example, the operation unit 140 is set to the position
where the volume is 0. Then, an operation reference audio signal is output from the reference
audio signal oscillating unit 210, and an operation adjustment audio signal is input from the
remote control device 100 to the audio signal processing device 200 and measured by the audio
measuring unit 220. Calibration is performed using the measurement result, whereby the audio
signal processing device 200 can detect the absolute value of the amount of operation of the
operation unit 140 on the remote control device 100 side.
[0042]
Next, the operation of the audio signal processing system 1000 according to the present
embodiment will be described based on the drawings. Here, the case where the voice adjustment
(adjustment of volume and sound quality) in the voice signal processing device 200 is remotely
controlled using the remote control device 100 will be described.
[0043]
The audio signal from the microphone 600 is input from the audio input unit 250 as a signal to
be processed by the audio signal processing device 200. The audio signal is processed by the
signal processing unit 260 and output from the audio output unit 270. Then, the audio signal is
amplified by the amplifier 400 and output from the speaker 500 into the gymnasium.
[0044]
A reference audio signal for operation is generated by the reference audio signal oscillating unit
210 of the audio signal processing device 200 separately from the audio signal to be processed,
and is input to the remote control device 100 through the audio transmission line 710. .
[0045]
The operator listens to the output voice from the speaker 500 in the gymnasium and operates
the operation unit 140 as needed.
10-04-2019
14
When the operation unit 140 is operated by the operator, the operation reference audio signal is
adjusted by the audio adjustment unit 120 according to the operation to generate an operation
adjustment audio signal, and the operation adjustment audio signal is an audio output unit. It is
output from 130.
[0046]
In the above operation, an audio signal for operation is not output from a speaker or the like.
Therefore, the operator does not listen to the audio signal for operation. The audio signal for
operation is exclusively used to indicate the amount of operation to the operation unit 140.
[0047]
The adjustment audio signal for operation generated by the remote control device 100 is input to
the audio signal processing device 200 through the transmission line 720, and is supplied to the
audio measurement unit 220. The voice measurement unit 220 measures the amount of change
of the adjustment voice signal for operation with respect to the reference voice signal for
operation. Here, as described above, the change amount of the volume and the frequency
characteristic is obtained as the information of the operation amount in the remote control
device 100. Then, the voice control unit 230 generates a control signal based on the amount of
change measured by the voice measurement unit 220 and supplies the control signal to the
signal processing unit 260. The signal processing unit 260 performs signal processing on the
input audio signal from the audio input unit 250, and the processed audio signal is output from
the audio output unit 270. Further, under the control of the audio control unit 230, the audio
information display unit 240 displays the adjustment state of the volume and the sound quality.
[0048]
According to the audio signal processing system 1000 of the first embodiment of the present
invention, the remote control device 100 adjusts the operation reference audio signal which is
the operation reference audio signal to adjust the operation adjustment audio. A signal is
generated and the operation adjustment audio signal is output to the audio signal processing
device 100. The audio signal processing device 100 performs signal processing based on the
amount of change of the operation adjustment audio signal with respect to the operation
reference audio signal. The present invention uses an audio signal for operation different from
10-04-2019
15
the signal processing target. The audio signal for this operation is used for a special purpose of
representing the amount of operation in the remote control device 100.
[0049]
The use of such an audio signal realizes remote control. Then, since an audio signal can be used
as a signal for remote control, an audio transmission line 710, 720 for transmitting audio is used
as a connection line between the remote control device 100 and the audio signal processing
device 200. For example, the existing wirings 1406 and 1407 shown in FIG. 14 can be used.
Therefore, it is not necessary to newly provide a control line for remote control by wiring work,
and an audio signal processing system capable of remote control can be easily installed with a
simple configuration.
[0050]
Further, according to the present embodiment, in the above-described example, it is possible to
use an existing mixer as the remote control device 100. Therefore, the existing mixer can be
effectively used, and remote control can be realized without providing a new configuration as the
remote control device 100. Furthermore, in the example of the present embodiment, since the
operation unit of the existing mixer can be utilized, a new operation unit is not necessary. Then,
as a result, it is possible to easily operate the new mixer (audio signal processing device 200)
without having to learn a new operation method.
[0051]
Further, in the present embodiment, the remote control device 100 may not be realized by a
mixer. The remote control device 100 may be a dedicated device. In this case, the remote control

Therefore, the remote control device 100 can be provided in a simple and inexpensive
configuration, and for example, it is possible to make the remote control device 100 with a
commercially available variable resistor or the like. Thus, in the present embodiment, the
advantage that the configuration of the remote control device 100 can be simplified is also

[0052]
Further, since the operation reference audio signal is generated in the audio signal processing
device 200 and the operation reference audio signal is supplied from the audio signal processing
device 200 to the remote control device 100, the operation reference audio is transmitted to the
remote control device 100 side. There is no need to provide a function to generate a signal, and
the configuration of the remote control device 100 can be simplified.
[0053]
Second Embodiment Hereinafter, an audio signal processing system according to a second
embodiment of the present invention will be described using the drawings.
The configuration of the audio signal processing system 1001 according to the present
embodiment is shown in FIG. As shown in FIG. 1, in the first embodiment, the reference audio
signal oscillating unit 210 is provided in the audio signal processing device 200, but as shown in
FIG. 3, in the present embodiment, The difference is that the reference sound signal oscillation
unit 210a is provided separately from the remote control device 100 and the sound signal
processing unit 200. The reference sound signal oscillation unit 210 a is, for example, a small
device provided with an oscillator, and is disposed near the remote control device 100, that is, at
the side of the stage, and connected to the remote control device 100. Further, in the audio signal
processing device 200, an operation reference audio signal is recorded, and this signal is used for
measurement. Even with such a configuration, since the operation reference audio signal is
supplied from the audio signal oscillating unit 210a to the remote control device 100, the same
effect as the effect described in the first embodiment can be obtained.
[0054]
Third Embodiment Hereinafter, an audio signal processing system according to a third
embodiment of the present invention will be described using the drawings. The configuration of
the audio signal processing system according to the present embodiment is shown in FIG.
Comparing the first embodiment and the third embodiment, as shown in FIG. 1, in the audio
signal processing system 1000 according to the first embodiment, the audio signal processing
device 200 transmits an audio signal of one channel. Was entered. On the other hand, as shown
in FIG. 4, in the audio signal processing system 1002 of the present embodiment, audio signals of
a plurality of channels are input to the audio signal processing device 201. The audio signal
processing system 1002 is configured as follows in order to remotely control the adjustment

processing of audio signals of a plurality of channels. In the following example, three
microphones are provided in the audio signal processing system 1002, and audio signals of three
channels are input to the audio signal processing device 201.
[0055]
As shown in FIG. 4, in the present embodiment, the audio signal processing device 201 is
provided with three audio input units 2501 to 2503 corresponding to audio input of three
channels. The signal processing unit 260 processes and mixes three-channel audio signals input
from the audio input units 2501 to 2503.
[0056]
Further, the audio signal processing device 201 is provided with an oscillation control unit 280
that controls the reference audio signal oscillating unit 210. The transmission control unit 280
controls the supply timing and the like of the operation reference audio signal to the remote
control device 101. Then, the oscillation control unit 280 generates a plurality of operation
reference speech signals separated by time division in the reference speech signal oscillating unit
210 in response to the speech signals of the plurality of channels processed by the speech signal
processing device 201. Let
[0057]
In the example of the present embodiment, the number of channels of the audio signal is 3, and
under the control of the oscillation control unit 280, three operation reference audio signals are
generated by the reference audio signal oscillating unit 210. These three operation reference
speech signals may be the same speech, but are generated in a separated state by time division
as described above. That is, as the three operation reference audio signals, the same audio signals
may be sequentially generated at timings shifted in time. These three control reference audio
signals are output to the remote control device 101.
[0058]
10-04-2019
18
As shown in FIG. 4, the remote control device 101 includes three audio input units 1101 to
1103, three audio adjustment units 1201 to 1203, and a mixing unit 150 for remote control of
three channels. There is. The voice input units 1101 to 1103 and the voice adjustment units
1201 to 1203 perform the same function as the voice input unit 110 and the voice adjustment
unit 120 in the first embodiment shown in FIG. 1. The mixing unit 150 mixes the operation
adjustment audio signals of three channels generated by the three audio adjustment units 1201
to 1203.
[0059]
Although not shown, the operation unit 140 is configured to be able to operate three channels.
Specifically, the operation unit 140 has three channel operation units (volume operation unit and
sound quality operation unit). Therefore, the three audio adjusting units 1201 to 1203 can be
individually operated using the operation unit 140 to individually adjust the operation reference
audio signals of three channels.
[0060]
In addition, the remote control device 101 according to the present embodiment may be
configured by a mixer as described above. The mixer is generally equipped with multiple
channels of input, audio conditioning and mixing. By these functions, the remote control device
100 corresponding to the plurality of channels described above can be realized. Therefore, the
present embodiment can be used as the remote control device 101 without modifying the
existing mixer.
[0061]
The configuration of the audio signal processing system 1002 according to the third embodiment
of the present invention has been described above. Next, the operation of the audio signal
processing system 1002 will be described based on the drawings.
[0062]
10-04-2019
19
As described above, under the control of the oscillation control unit 280, the three-channel
operation reference audio signals separated by time division are output from the reference audio
signal oscillating unit 210 and input to the audio input units 1101 to 1103, respectively. Ru.
Then, in response to the operation to the operation unit 140, the operation reference audio
signals of three channels are respectively adjusted by the audio adjusting units 1201 to 1203,
and three operation adjusting audio signals are generated. These three adjustment audio signals
for operation are supplied to the mixing unit 150 and mixed.
[0063]
The operation reference speech signals of the three channels are separated by time division as
described above, and are shifted in time. Therefore, the three operation adjustment audio signals
are also shifted in time. As a result of the mixing of these signals, in one signal after mixing, the
three operation adjustment audio signals are aligned with time lag. The adjusted audio signal for
operation of one channel after such mixing is output from the audio output unit 130.
[0064]
The adjustment audio signal for operation after the above mixing is input to the audio signal
processing device 201 and input to the audio measurement unit 220. In the voice measurement
unit 220, first, the inputted adjustment voice signal for operation is separated into three
adjustment voice signals for manipulation before mixing. As described above, the three operation
adjustment audio signals are temporally offset, and this offset is used to perform separation.
[0065]
Thereafter, the same processing as that of the first embodiment is performed individually for
each of the three channels. That is, the amount of change of the adjustment audio signal for
operation with respect to the reference audio signal for operation is measured in each channel,
and the control signal is generated by the audio control unit 230 from the amount of change. The
signal is processed.
[0066]
10-04-2019
20
By such an operation, the audio signal processing system 201 can individually adjust three
channels of audio. For example, in the remote control device 101, it is assumed that the
operation unit corresponding to the first channel is operated in the operation unit 140. In this
case, the audio adjustment unit 1201 of the first channel adjusts the operation reference audio
signal according to the operation. Also in the signal after mixing in the mixing unit 150, the
operation adjustment audio signal of the first channel changes with respect to the operation
reference audio signal. The adjusted audio signal for operation of the first channel is acquired by
the audio signal processing device 201 and used for signal processing. As a result, the operation
on the first channel is reflected in the signal processing.
[0067]
According to the audio signal processing system 1002 of the third embodiment of the present
invention, the remote control device 101 adjusts the plurality of operation reference audio
signals separated by time division to adjust the plurality of operations. An audio signal is
generated, and the plurality of operation adjustment audio signals are mixed and output to the
audio signal processing device 201. The audio signal processing device 201 separates the mixed
signal into a plurality of operation adjustment signals and performs processing for each channel.
Therefore, audio signal processing of a plurality of channels can also be preferably remotely
controlled. Furthermore, as described above, according to the present invention, for example, a
general mixer can be used as a remote control device.
[0068]
In the above description of the present embodiment, oscillation control unit 280 generates a
plurality of operation reference audio signals separated by time division corresponding to audio
input of a plurality of channels to audio signal processing apparatus 201. It has been described
that the reference audio signal oscillating unit 210 is controlled to As a modification, a plurality
of operation reference audio signals separated by frequency division may be generated. In this
case, the adjustment audio signal for operation after mixing is also divided into plural based on
the frequency on the audio signal processing device 201 side. As a further modification, a
plurality of operation reference audio signals separated by time division and frequency division
may be generated. Also in these cases, the same effects as the above-described effects can be
obtained.
10-04-2019
21
[0069]
Further, in the example of the present embodiment, although audio signals of three channels are
input to the audio signal processing apparatus 201, it is a matter of course that the number of
channels is not limited to three. The number of adjustment signals may be set.
[0070]
Fourth Embodiment Hereinafter, an audio signal processing system according to a fourth
embodiment of the present invention will be described with reference to the drawings.
The configuration of the audio signal processing system according to the fourth embodiment is
shown in FIG. Comparing the third embodiment and the fourth embodiment described above, in
the third embodiment, audio signals of a plurality of channels are input to the audio processing
device 201. In the fourth embodiment, audio signals of a plurality of channels are further output
from the audio signal processing device 202. The audio signal processing system is configured to
be able to remotely control not only the plurality of channels on the input side but also the
plurality of channels on the output side.
[0071]
Referring to FIG. 5, in the example of the present embodiment, an audio signal of m channels is
input and an audio signal of n channels is output. m voice input units 2501 to 250 m are
provided corresponding to m channel input voice signals. Further, n sound output units 2701 to
270 n are provided corresponding to the n-channel output sound signals.
[0072]
The signal processing unit 260 individually adjusts the m-channel input audio signals. The
adjusted m-channel audio signal is mixed by the signal processing unit 260, and an output nchannel audio signal is generated therefrom. Further, the n-channel output audio signals are
individually adjusted and output to the audio output units 2701 to 270 n. Under the control of
the oscillation control unit 280, the reference sound signal oscillating unit 210 generates the
operation reference sound signal separated into the number corresponding to the total number
of channels of the input and output. Here, it is assumed that the total number of channels is X (=
10-04-2019
22
m + n). The remote control device 102 has X voice input units 1101 to 110X and voice
adjustment units 1201 to 120X corresponding to the total number of channels X. The X-channel
operation reference audio signal is adjusted individually by the audio adjusting units 1201 to
120X according to the operation on the operation unit 140, as in the above-described
embodiment.
[0073]
With such a configuration, it is possible to individually adjust the m-channel input voice and the
n-channel output voice by remote control. For example, one channel on the output side is n1. It is
assumed that the operation unit 140 is operated in the remote control device 102, and the
operation amount corresponding to the channel n1 is changed. In response to this operation, the
operation reference audio signal of channel n1 is adjusted. Then, the operation adjustment audio
signal is mixed with another signal and sent to the audio signal processing device 202 side. On
the audio signal processing device 202 side, the operation reference audio signal of channel n1 is
extracted and reflected in the processing of the output audio signal of channel n1. Also in the
audio signal processing system 1003 of the fourth embodiment of the present invention, effects
similar to those of the third embodiment can be obtained, and audio signal processing of a
plurality of channels can also be preferably remotely controlled.
[0074]

the operation device 101 and the audio signal processing unit 201. As described in the second
embodiment, the reference sound signal oscillating unit 210a is provided in the vicinity of the
remote control device 101. Even with such a configuration, the operation reference audio signal
is input from the audio signal oscillating unit 210a to the remote control device 101, so that the
above-described effect of the present invention is exhibited.
[0075]
10-04-2019
23
Also in the fourth embodiment shown in FIG. 5, the reference audio signal oscillating unit may be
provided outside the reference audio signal processing apparatus as in the fifth embodiment.
This point is the same in any of the other embodiments described below.
[0076]

display device 800A are provided as a pair at point A, and the remote control device 100B and
the display device 800B are provided as a pair at point B. Further, as shown in FIG. 8, the audio
signal processing device 203 is connected to the remote control devices 100A, 100B and the
display devices 800A, 800B installed at each installation point. The remote control devices 100A
and 100B have the same configuration and function as the remote control device 100 in the first
embodiment.
[0078]
As mentioned above, a large scale conference facility is mentioned as an example by which a
remote control is installed in a plurality of points. Suppose that two conference rooms are
connected in such a facility. It is assumed that the remote control device is installed in these two
conference rooms. In this case, it becomes useful to remotely control one audio signal processing
device from the two remote control devices.
10-04-2019
24
[0079]
As shown in FIG. 7, the audio signal processing device 203 includes audio measurement units
220A and 220B and operation detection units 291A and 291B in order to cope with remote
control from the two remote control devices 100A and 100B. An operation selection unit 292 is
provided. The voice measurement units 220A and 220B have the same functions as the voice
measurement unit 220 in the first embodiment. The operation detection units 291A and 291B
are connected to the voice measurement units 220A and 220B, the operation detection unit
291A is connected to the display device 800B at B point, and the operation detection unit 291B
is connected to the display device 800A at A point It is connected.
[0080]
The operation detection unit 291A detects that there has been a remote operation from the
remote control device 100A when there is a change in the amount of change which is the
measurement result of the voice measurement unit 220A, and the operation amount of the
remote control device 100A at point A. Is output to the display device 800B at point B. On the
other hand, when there is a change in the amount of change which is the measurement result of
the voice measurement unit 220B, the operation detection unit 291B detects that there is a
remote control from the remote control device 100B at the B point, and the remote control at the
B point It outputs to the display apparatus 800A of A point as information of the operation
amount of the apparatus 100B. In this way, the display device at each point is provided with
information on the amount of operation by the remote control device at another point
(hereinafter referred to as information on the other point operation amount).
[0081]
The operation selection unit 292 is connected to the operation detection units 291A and 291B
and the voice control unit 230. The operation selection unit 292 selects the remote control from
any one of the remote control devices 100A and 100B. Here, the operation selection unit 292
selects the last one of the remote control devices 100A or 100B that has been operated. Then,
based on the selection result, the operation selection unit 292 uses the change amount measured
by the sound measurement unit 220A or 220B (that is, the change amount of the operation
adjustment sound signal with respect to the operation reference sound signal) as the operation
10-04-2019
25
amount information. It outputs to the control unit 230.
[0082]
The voice control unit 230 generates a control signal of the signal processing unit 260 based on
the amount of change input from the operation selection unit 292, and supplies the control
signal to the signal processing unit 260. Further, the voice control unit 230 outputs information
of the remote control operation amount applied by the signal processing unit 260 (hereinafter
referred to as information of the applied operation amount) to the display devices 800A and
800B. .
[0083]
As described above, the information on the amount of applied operation corresponds to the
amount of operation of the remote control device 100A or 100B that was operated last. The
applied operation amount is also information of signal processing amount, that is, adjustment
amount of sound volume and sound quality. Similar information is also supplied from the voice
control unit 230 to the voice information display unit 240 for display control. The information of
this display control may also be supplied to the display devices 800A and 800B as illustrated.
[0084]
Further, in the audio signal processing device 203, the transmission unit control unit 280a is
configured to supply the reference audio signal oscillating unit 210 so as to supply the operation
reference audio signal to each of the remote control devices 100A and 100B at the A point and
the B point. Control.
[0085]
The display devices 800A and 800B have built-in information processing functions such as a
computer, etc., and process information supplied from the audio signal processing device 203 to
perform display operation.
Then, the display devices 800A and 800B display information on which of the remote control
10-04-2019
26
devices 100A and 100B has been remotely operated, and information on the amount of
operation by the remote operation.
[0086]
More specifically, as described above, the display device 800A is supplied with the information of
the applied operation amount and the other point operation amount from the audio signal
processing device 203. The applied operation amount is an operation amount applied to signal
processing in the audio signal processing device 203, and specifically, is an operation amount of
the last one of the two points that was remotely operated. The other point operation amount is
information of the operation amount of the remote operation at the other point, and in this case,
is the operation amount of the point B.
[0087]
The display device 800A compares the applied operation amount with the other-point operation
amount. If the two match, the operation amount of the other point (point B) is applied by the
audio signal processing device 203. If the two are different, the operation amount at the point A
where the display device 800A is installed is applied. Therefore, the display device 800A
determines which of the two-point operation is being applied, based on the comparison result of
the applied operation amount and the other-point operation amount. Then, the display device
800A displays the information indicating the magnitude of the applied operation amount
together with the information indicating the determination result of the operation point.
[0088]
The same applies to the display device 800B. However, while the other point operation amount
at point B is supplied to the display device 800A, the other point operation amount at point A is
supplied to the display device 800B. Then, the other point operation amount of the point A is
compared with the applied operation amount.
[0089]
10-04-2019
27
Next, the operation of the audio signal processing system 1005 according to the sixth
embodiment will be described based on the drawings. From the remote control devices 100A and
100B at the A point and the B point, the adjustment voice signal for operation generated based
on the operation of the operation unit 140 is output to the audio signal processing device 203.
[0090]
In the audio signal processing device 203, the audio measurement units 220A and 220B
measure the adjustment audio signal for operation and the reference audio signal for operation
input from each of the remote control devices 100A and 100B, and adjust the operation for the
reference audio signal for operation The amount of change in the audio signal is determined as
the amount of operation. The operation detection units 291A and 291B detect whether or not
there is a change in the amount of change which is the measurement result of the voice
measurement units 220A and 220B. Then, when there is a change in the amount of change, the
operation detection units 291A and 291B detect that there has been a remote operation from the
remote control devices 100A and 100B, and display information on the amount of operation of
the remote control devices 100A and 100B. Output to the devices 800A and 800B.
[0091]
At this time, information on the other point operation amount by the remote control device at
another point is sent to the display device at each point. For example, when the remote control is
performed from the remote control device 100B at point B, the amount of change measured by
the voice measurement unit 220B fluctuates. At this time, the operation detection unit 291B
detects that there is a remote control from the remote control device 100B at the point B from
the fluctuation of the change amount measured by the voice measurement unit 220B, and the
operation detection unit 291B of the remote control device 100B at the point B Information on
the amount of operation is output to the display device 800A at point A as information on the
amount of operation at another point.
[0092]
The operation selection unit 292 selects the last one of the remote control devices 100A or
100B, and based on the selection result, the operation amount measured by the voice
measurement unit 220A or 220B is sent to the voice control unit 230. Output. For example,
10-04-2019
28
when the remote control is performed from the remote control device 100B at point B last, the
operation selection unit 292 outputs the operation amount measured by the voice measurement
unit 220B to the voice control unit 230.
[0093]
Then, the voice control unit 230 generates a control signal based on the operation amount input
from the operation selection unit 292, and supplies the control signal to the signal processing
unit 260. Further, the voice control unit 230 outputs information of the applied operation
amount applied by the signal processing unit 260 to the voice information display unit 240 and
the display devices 800A and 800B.
[0094]
By the operation of the audio signal processing device 203 described above, the information on
the applied operation amount and the other point operation amount is supplied to the display
devices 800A and 800B at the A and B points. The applied operation amount is the operation
amount applied to the signal processing as described above, and more specifically, is the
operation amount of the remote operation performed last. The other point operation amount is
the operation amount of the other point, the operation amount of the B point for the display
device 800A, and the operation amount of the A point for the display device 800B. Each of the
display devices A and B compares the applied operation amount with the other point operation
amount and performs display processing based on the comparison result.
[0095]
FIG. 9 shows a display example of the display devices 800A and 800B together with an operation
example of the remote control devices 100A and 100B. Here, volume control is taken as an
example. The operation example is represented by the positions of the volume control knobs
801A and 801B. In addition, each of the display devices 800A and 800B includes a plurality of
LEDs 802A and 802B arranged in a circle.
[0096]
10-04-2019
29
In FIG. 9, the operation amount of the remote control device 100A is level 3, and the operation
amount of the remote control device 100B is level 2. It is assumed that the remote control device
100A is operated last. In this case, in the display device 800A, the applied operation amount is at
level 3, the other-point operation amount is at level 2, and the two do not match. This indicates
that the operation is finally performed at the point A where the display device 800A is installed
and is reflected in the processing of the signal processing device 203. Therefore, in this case, the
display device 800A turns on the LED 802A in green (hatched in the figure) up to level 3. Green
indicates that the operation has been performed at the display device installation point.
[0097]
On the other hand, in the display device 800B, the applied operation amount is at level 3, the
other-point operation amount is at level 3, and both are in agreement. This indicates that the
operation is finally performed at the other point A, which is reflected in the processing of the
signal processing device 203. Therefore, in this case, the display device 800B turns on the LED
802B in red (represented by meshed lines in the figure) up to level 3. Red indicates that the
operation was performed at another point. In this manner, the display devices 800A and 800B
can display the information of the applied operation amount in the signal processing device 203
together with the information on which point the operation has been performed.
[0098]
FIG. 10 shows another operation example and display example. It is assumed that the remote
control device 100B is operated from the state of FIG. 9 and the operation amount of the
operation knob 801B changes to level 4. In this case, in the display device 800A, the applied
operation amount is at level 4 and the other-point operation amount is also at level 4, and both
are in agreement. Therefore, the display device 800A changes the LED 802A to lighting of level 4
and changes the display color to the red of the other point operation.
[0099]
Further, in the display device 800B, although the applied operation amount is at level 4, the
other-point operation amount remains at level 3, and the two do not match. Therefore, the
display device 800B changes the LED 802B to lighting of level 4 and changes the display color to
10-04-2019
30
green. In this manner, the display devices 800A and 800B can display the information of the
operation point together with the operation amount in response to the remote operation at any
point.
[0100]
According to the audio signal processing system 1005 of the sixth embodiment of the present
invention, the plurality of display devices 800A and 800B are remote controllers at a plurality of
installation points (point A and point B). Information is provided on the display devices 800A and
800B, together with the operation information of the remote control devices at other points, and
the information of the operation amount by the remote control device on which the operation is
performed is displayed. Therefore, the operator of each of the remote control devices 800A and
800B can adjust the voice while confirming the operation information of the remote control
